基于PSOC6开发板模拟I2C 解X-NUCLEO-IKS01A3的LPS22HH [复制链接]

本次解析的是LPS22HH 芯片，接口还是IIC，驱动还是按照原来的，先实验读ID；

 uint8_t LPS22HH_Read_Date(uint8_t SlaveAddress, uint8_t RegAddress)
{
    uint8_t recvDate;
    uint8_t succ, stime=0;
    
    I2C_Start();
    succ = I2C_Send_Byte(SlaveAddress & 0xfe);
    while((succ !=1)&&(stime<3))
    {
        I2C_Stop();
        I2C_Start();
        succ = I2C_Send_Byte(SlaveAddress & 0xfe);  //写
        stime++;
    }
    I2C_Send_Byte(RegAddress);
    
    I2C_Start();
    I2C_Send_Byte(SlaveAddress | 0x01);  //读
    recvDate = I2C_Read_Byte(1);   //NACK
    I2C_Stop();
    return recvDate;
}

printf("PID_LPS = %X\r\n",LPS22HH_Read_Date(LPS22HH_ADD, 0x0F));
